Application filed September 20, 1912. Serial No. 721,373.

To all whom it may concern:

Be it known that I, SAMUEL C. Srnnon, a citizen of the United States, residing at Anderson, Madison countyy-Indiana, have in vented certain new and useful Improvements in Paper Receptacles or Cartons, of which the following is a specification.

My invention relates to paper receptacles or cartons of the knock-down or collapsible type and designed for use in the packing of merchandise, for instance candy, in boxes or containers of square or rectangular shape.

The object of my invention is to make receptacles or cartons of this character which shall be comparatively simple and inexpensive of manufacture, and at the same time capable of being collapsed withina small compass. p v

In the drawings Figure-1 is a plan view of the blank from which my carton is made; Fig. 2 a plan viewof the carton collapsed; Fig. 3 a sectional plan of the carton collapsed; Fig. 4: a top-edge view of the carton collapsed; Fig. 5 a perspective ofa box or container of square form in which a series of my cartons is nested; Fig. 6 a bottom plan view of one of the cartons; Fig. 7 a perspective thereof in erected form; and Fig. 8 a detail view showing the carton in the act of being collapsed.

My receptacle or carton is made from the blank shown in Fig. l, the same being made of suitable paper board and divided by means of score lines into the three side walls A, B and G and a triangular-shapedbottom wall D. The side walls are connectedor hinged together along the parallel score lines a and 6 extending transversely ofthe blank and the bottom wall is connected or hinged to the side wall C at the score line d. In the present instance the two side walls A and B are square and of equal area, while the third side wall C, although rectangular, is oblong and of greater area than the other two side walls.

The bottom wall D is bisected by a score line at which extends at right angles to the score-line (Z and continues centrally across to the side wall 0, thereby dividing the same into two sections. Each of these sections is provided with a score-line c which extends obliquely across the blank, that is, runs oblique to the parallel score-lines a, b and d. This oblique score-line extends upwardly and inwardly from the outer lower corner formed by the attached side and bottom walls to the opposite edge of the side wall, terminating at a point intermediate the score-line d and the outer upper corner. These two oblique score-lines extend at equal angles from the outer lower corners of their sidewalls and such lines, if further extended (as for instance, if the carton were made higher than illustrated, of which my invention permits) would meet at the score line all extended.

The bottom wall D is provided on its two free edges with the two flaps D for attachment by means of an adhesive to the side walls A and B along their bottom edges. The side wall C is provided with a flap C" for attachment by means of an adhesive to the outer vertical free end of the side wall A. When the receptacle or carton is set up ready for use it assumes the form clearly illustrated in'Fig. 7, the same being substantially triangular in horizontal section and therefore capable of being nested within the square box E shown in Fig. 5, wherein a series of eight similar cartons are shown to completely fill the box.

In collapsing the'carton the same is forced inwardly by pressure against a point substantially corresponding to the intersection of the two score-lines d and d, whereupon the two sections of the bottom wall and the innermost portions of the side wall C fold inwardly. Continued movement of these parts brings the carton to the collapsed condition shown in Figs. 2, 3 and at, which is the condition assumed by cartons after manufacture and up to the time of use. In assembling or erecting the cartons the two side walls A and B are drawn apart and the bottom D and side wall 0 are pressed downwardly and outwardly until the carton snaps into the erected condition shown in Fig. 7, which condition is maintained except when a positive force is applied, as in the act of collapsing the carton.

It will be understood that the construction of filler shown permits of the .same being made of any desired height, even to such extent that the two oblique score-lines 0 which proceed upwardly and inwardly at and the adjacent portion of the obliquely scored side wall being folded inwardly in one plane against the other half of the bottom wall and the corresponding portion of such side wall adjacent to it, such fold lying between the unscored walls'and remaining portions of the obliquely scored side walls and eac'h unscorcd side wall and the portion of the scored Wall adjacent it lying in one plane.

2. A collapsible paper receptacle comprising three connected rectangular sidewalls, and a bottom wall hinged at its edges .to :the bases of said side walls which in shape isan isosceles right-angled triangle; saidbottoin being scored on a folding line perpendicular to its longer side and extending centrally across to the outer edge of the side wall-hinged to said side; such side wall being obliquely scored on folding lines extending from the extremities of its base and converging symmetrically toward said central score line, and the half of each bottom walland the adjacent portion of the obliquely scored side wall being folded inwardly in one plane against the other half of the bottom wall and the corresponding portion of such side adjacent to it, such fold lying between the unscored walls and the remaining portions of the obliquely scored side walls and each unscored side wall and the portion ofthe scored wall adjacent it lying in one plane.

3. A collapsible paper receptacle made from a blank divided into three side walls by parallel score lines, and into a triangular shaped bottom wall hinged to one of :the

side "walls upon "a score line "at right angles to said parallel score lines, said bottom wall having centrally thereof a scored ifolding line extending-across the center ofthe side wall to which it is connected to the outer edge thereof; and said last-mentioned side "wall having two oblique scored folding lines 'whicheXtend from the corners formed by side walls one o'f said s ide walls being substantially centrally vertically scored on a folding line to formtwo (sections, and the bottom wall being similarly scored on a folding line aiiliich is a continuation of the score line .of the side well; each section of said side -wall.being scored on a folding line oblique to said central score line and run- :ning from the 10m corner of said side wall to the opposite upper edge thereof at a point thereon intermediate its length, said oblique score lines proceedingat equal angles toward the central score line, and the halfiof each bottom wall and the adjacent portion of the obliquelyscored side wall being folded inwardly, in one plane against .the other half of the'bottom wall a and the corresponding portion o f vsuch side adjacent "to it, such fold lying between the uns'cored walls and remaining portions of theobliq uely scored side Walls and each unscored side wall and the portion of ithescored wall adjacent it lying in one plane.v
